For those familiar with the series, this is another book about Greg's misadventures. In this book, he does come off as slightly less selfish than in previous ones, but he still looks out for himself. The book doesn't deal with a lot of school popularity issues as do previous books. Rather, if focuses more on small details about Greg's life. Maybe that's why it doesn't seem as interesting.
The laughs are there, but there weren't any really great moments. I think the closest I came to laughing out loud was the scene about his doll's revenge. Beyond that, there's the usual bits with Rowley, a little with his older brother, his younger brother Manny is still a terror (why he's not disciplined at all I don't get), and his parents still don't get him.
The kids I spoke to enjoyed this book, but not as much as earlier versions. So I guess that's consistent. The author stated that he was inspired to write this book when he himself was snowed in or trapped away from home. Frankly, this book seems like something that would come out of that rather than serious creative juices. Hopefully for fans of the series this is just a blip and not the beginning of the end of the comedy.
